+Subject: [PATCH] Improve Reproducibility for src package
+
+Improve reproducibility for intel-graphics-compiler-src package.
+needs to pass build path as environment variable to the build.
+this only works on bison 3.7 onward, hence check for bison version
+before adding the flags.
+Upstream-Status: Inappropriate [applying --file-prefix-map in such way does not work for upstream]
+Signed-off-by: Lee Chee Yang <chee.yang.lee@intel.com>
